What does the +0.25mm sizing mean for these main bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper oil clearance and fit.

Are these bearings suitable for high-performance or heavy-duty applications?

These bearings are made from a bi-metal aluminum composite and are described as ideal for medium-load engines. For high-performance or heavy-duty applications, it's always best to consult King Engine Bearings' specific product lines designed for those uses.

What is the benefit of a lead-free composite bearing?

Lead-free bearings are considered environmentally safer than traditional lead-based bearings. This material choice also contributes to the bearing's performance characteristics in medium-load engine applications.

About this part

Product Details

If you're rebuilding the bottom end of a Chrysler 2.7L engine, this main bearing set from King Engine Bearings is a solid option. These are the main bearings, which support the crankshaft within the engine block. King has been specializing in bearings since 1960, focusing on making them well-built and reliable.

This particular set is made from a bi-metal aluminum material, which is a lead-free composite. This makes them environmentally safe and ideal for engines that handle medium loads, like many common passenger car applications. The bearings in this set are sized at +0.25mm, meaning they are meant to be used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. This sizing is critical for achieving proper oil clearance and ensuring the engine runs correctly after assembly.

This set fits a range of Chrysler and Dodge vehicles equipped with the 2.7L engine, including models like the 2005-2010 Chrysler 300, 2001-2010 Chrysler Sebring, and 2006-2010 Dodge Charger. Always ensure you consult your vehicle's service manual for the correct bearing size and installation procedures.
